serialization_map | [R] | A map of the serialized columns for this model. Keys are column symbols, values are serialization formats (:marshal, :yaml, or :json). |
serialization_module | [RW] | Module to store the serialized column accessor methods, so they can call be overridden and call super to get the serialization behavior |
Copy the serialization format and columns to serialize into the subclass.
# File lib/sequel/plugins/serialization.rb, line 42 42: def inherited(subclass) 43: super 44: sm = serialization_map.dup 45: subclass.instance_eval{@serialization_map = sm} 46: end
The first value in the serialization map. This is only for backwards compatibility, use serialization_map in new code.

Create instance level reader that deserializes column values on request, and instance level writer that stores new deserialized value in deserialized columns
